Heading C7E. 1, 3 dicyclohexyl -2-thiourea and/or cyclohexyl thiourea are used as corrosion inhibitors for ferrous or Al metal. The inhibitor may be used in a bath for the pickling of said metal, e.g. of H 2 SO 4 , HCl, HNO 3 , H 3  PO 4 , or acetic acid, or in a system wherein a-corrosive liquid is passed through ferrous or Al pipes, e.g. in an oil field acidizing operation wherein HF or HCl is injected into a well to open underground channels or in the oil industry where brine is maintained in contact with metal. Amounts of 0À0002 wt% to 0À2% are sufficient to inhibit corrosion. In an oilproducing well, a solution of the inhibitor in EtOH, MeOH, or i-PrOH may be poured into the well tubing, or the inhibitor may be dropped in in a solid form bound in a disintegrable binder such as lead oxide, petroleum wax or asphalt.

Abstract: 987,367. Doffing apparatus. WILLCOX & GIBBS SEWING MACHINE CO. Ltd. Dec. 6, 1963 [Dec. 19, 1962], No.48220/63. Addition to 965, 166. 'Heading D1D. In the apparatus of the parent Specification, instead of using the means urging the ejector member upwardly (e.g. the spring 40) to break the driving connexion between the bobbin and the spindle as the holding means is released (e.g. as the follower 47 slips over the bottom edge of the cam-track 46), a cam 49 is provided operable in the doffing-position positively to move the ejector upwardly and thereafter to release the ejector to be moved upwardly. Fig. 4 shows the lower part of the track 46, and the follower 47 held at the bottom end 46b of track just as doffing is about to take place. As the carriage continues its travel, and the star wheel 56 further rotates the sleeve,the follower moves into engagement with a cam 49 which forces it upwardly against an inclined part 46d of the track, which rising movement breaks the driving connexion. As the sleeve rotates further, the follower slips past the part 46d for the spring to raise the ejector and doff the bobbin.

Title: Improvements in or relating to magnetic data storage arrangements
Inventor: MORRIS RICHARD MICHAEL
IPC: G11C7/02
Filed: 1964-11-27
Abstract: 1,062,328. Read-only stores. GENERAL ELECTRIC CO. Ltd. Nov. 19, 1965 [Nov. 27, 1964], No. 48312/64. Heading G4A. [Also in Division H3B] In an arrangement for discriminating between true signals and noise when a voltage is induced in a sense wire by reading out one or more magnetic storage cores of an array, the induced voltage is integrated with respect to time and is then applied to an amplifier, the voltage output of which is determined by this integral. A 15 x 15 storage array is described in which each storage device 1, 2 ..., Fig. 1, represents a binary word. As shown, each device comprises a magnetic storage core 27, 33 ... threaded by column and row selection wires 11, 12, 17, 18 ..., a non-saturable transformer core 26 being coupled by a closed wire loop to the respective storage core. Eighteen sense wires 22, 23 corresponding respectively to the eighteen digit positions of stores binary words are provided, each wire being connected to a respective signal discriminator and threading selected transformer cores in the array. Thus, if the array is addressed for readout of a given binary word, a true signal output is induced in those sense wires threading any transformer of a storage core which is switched by coincident row and column currents. Noise is induced in any other sense wire which threads a transformer of a storage core disturbed by row or column currents alone. The signal discriminators, Fig. 2, each determine whether the induced voltage in its respective sense wire is a true signal or noise by using an inductor 40 or a capacitor to integrate the voltage with respect to time, the integration being applied to an amplifier 41 comprising transistors 42, 43 which produces an output in lead 57. This output, which corresponds in amplitude and polarity to the integrated signal, is applied to an R-C combination 59, 60, the voltage across resistor 60 switching off a normally conductive transistor 62 if the voltage is of polarity characteristic of readout. With the transistor 62 off, a voltage is obtained at output terminals 64, 66 until the voltage in the R-C circuit falls below a threshold value. Consequently, this output voltage has a duration which is longer for true signals than for noise. Final discrimination may be obtained by applying the output signal to an AND gate, the other input of which is supplied by a clock pulse.
